If you’re looking to do a solo retreat, you can meet with Tucker on video chat (generally Monday, Wednesday & Friday). Payment for this is by donation. If you’re looking for a place to do solo retreat, the two centers Tucker works with most are Diamond Mountain and Dharma Treasure, both fairly low-cost facilities in Arizona. Diamond Mountain’s campus is thousands of acres, so your retreat can be extremely secluded; you might go a week without seeing another person. If you are an advanced practitioner looking for deep retreat, this is for you. If you are looking for a quiet retreat center that isn’t quite as secluded, Dharma Treasure has a number of staff and other retreatants living on a property of just a few acres. Dharma Treasure also allows retreatants to work on the property in lieu of payment, such that it might be possible to do a retreat there for free.
